Small magnitude 3.2 quake hits 15 miles north of Ukiah, California early afternoon3.2 quake 15 miles N of Ukiah, California, 2 Nov 2.22 pm (GMT -8)
A magnitude 3.2 earthquake was reported only 8 minutes ago by the United States Geological Survey (USGS), considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a very shallow depth of 4.1 miles beneath the epicenter early afternoon on Monday 2 November 2020 at 2.22 pm local time. The magnitude, exact location of the epicenter, and depth of the quake are likely to be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service at VolcanoDiscovery identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.2 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Towns or cities near the epicenter where the quake might have been felt, based on preliminary calculations, include Willits (pop. 4,900) located 7 miles from the epicenter and likely affected by weak shaking, Redwood Valley (pop. 1,700) located 7 miles from the epicenter and likely affected by weak shaking, Ukiah (pop. 15,900) located 15 miles from the epicenter and likely affected by very weak shaking, and Fort Bragg (pop. 7,300) located 31 miles from the epicenter and likely affected by very weak shaking.
